Steam from under the bonnet!
"Stop and get the cooling system looked at now."
Today's vehicles are equipped with complex cooling systems.
Due to rising fuel costs and economic times, manufacturers are designing smaller engines but asking them to deliver more power and better performance.
With these new designs came the alloy cylinder head and electrolysis.
Electrolysis is a stray electrical current produced when the engine is operating. This stray current produces a devastating corrosive effect on alloys, like a cancer slowly eating away at unprotected parts of the vehicle, such as the alloy cylinder head, water pump, radiator and many water fittings that are vital components of your car's cooling system.
To be kept in peak running condition, a cooling system must maintain the correct operating temperature and reduce corrosion. It also involves controlling these stray currents (the unseen danger to modern cooling systems).
